virustotal.com
Runs a file, URL or hash past seventy-odd antivirus engines at once.
Upload a file or paste a URL and it returns each engine's verdict side by side, plus behavioural analysis, embedded URLs and every previous time the same hash was seen. Searching by hash rather than uploading is the move for anything sensitive — it tells you what is known about the file without the file leaving your machine. Now owned by Google, and free for interactive use.
Questions
Works the moment the page loads. No account, no email, no trial. Anything you upload is shared with the security industry and may be downloadable by researchers, so never submit a confidential document.
Yes. VirusTotal sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
